{wiki=Aspherical_space}
Aspherical space is a term used in topology, a branch of mathematics that studies the properties of space that are preserved under continuous transformations. Specifically, an aspherical space is a manifold (or more generally, a topological space) whose universal covering space is contractible. This means that the universal cover does not have any "holes"; it can be continuously shrunk to a point without leaving the space.
